MACHINE FOR DELINTING COTTON-SEEDS.

SPECIFICATION forming part of Letters Patent No. 534,804, dated February 26, 1895. Application' nea April so, 1894. i serial No. 509,442. (no man To all whom it may concern:

Be it known that I, MICHAEL MORAN, ofthe city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Machines for Delinting Cotton-Seeds, of which the following is a full, clear, and eX- act description, reference being had to the accompanying drawings, forming part of this specication.

My present invention relates to certain im'- provements in machines for removing the lint from cotton seeds. This machine might be used for polishing grain, such as wheat or oats, and the portions removed from the grain carried off in asimilar manner to the wayin which the lint is carried from the cotton seeds.

My present invention consists in features of novelty hereinafter fully described and pointed out in the claims.

Figure I, is a top or plan view of my improved machine, with part of the top of the casing removed. Fig. II, is a top View of the discharge valve removed. Fig. III, is an enlarged side View of one of the blocks. Fig. IV, is a transverse section taken on line IV-IV, Fig. III. Fig. V, is a similar view taken on line V-V, Fig. III, showingthe rivet or bolt inserted in the opposite direction. Fig. VI is a side elevation, part in section. Fig. VII, is in part a vertical transverse section taken on line VII-VII, Fig. VI, the cylinder being shown in elevation. Fig. VIII is a detail vertical section taken on line VIII-VIII, Fig. VI. Fig. IX, is adetail vertical transverse section of one of the cylinders. Fig, X is a detail top view of one of the cylinders. Fig. XI is a diagram showing the manner of arranging the brushes or bristles on the cyl' inders and the relation thereto of the comb. Fig. XII is an enlarged detail section showin g part of one of the combs andthefair pipe.

Referring to the drawings, l represents the closed casing or housing of the machine, supported on suitable legs 2, and having preferably a glass top 3, which permits an observation of the interior of the machine.

4 represents the feed hopper which may be provided with spiked rollers 5to form a forced feed, the rollers being geared together, as shown at 6 Fig. I, so as to be turned toward each other. On one of the spiked rollers 5 is a pulley 7 having frictional or other gear con nection 8 with the cylinders of the machine.

Within the housing are a number of cylinders 9, journaled in the sides of the housing, as shown at 10, Fig. VII. The peripheries of these cylinders carry brushes or bristles 11, preferably of wire, bent as shown in Fig. VIII and passed through perforations made in the outer Wall of the cylinders to re ceive the bristles, as shown in Fig. X. One row of perforations is staggered with the adjacent rows, so that the bristles of the different rows Will be arranged in staggered form. The bristles of every other row are shorter than the bristles of the intermediate rows, as shown in Fig. IX and in the diagram Fig. XI. Over each cylinder is a comb l2, between the teeth of which the longer bristles on the cylinder pass, as shown in the diagram, so that the teeth of the comb Will effectually remove the lint from the surface of the cylinder.

Arranged within the housing are air pipes 13. These air pipes extend through the sides of the housing and are open at their ends, and each pipe has a slot running its entire length Within the housing, so that the air can pass from the tubes into the housing to supply the vacuum formed by the fan 14.

The slots in the tubes 13 are so arranged as to direct the air current in the most advantageous direction for carrying the lint toward the rear of the machine, where it escapes through the fan While the seeds escape through a chute 15 into a discharge valve 16 (see Figs. II and VI), the valve being turned by suitable means. The course of the air as it issues from the pipes 13 is indicated by arrows in Fig. VI.

To prevent air entering around the journal bearings of the cylinders 9, I employ rings 17 which are set into the heads of the cylinders, as shown in Fig. VIII, and which are held `outwardly against the inner wall of the housing by means of springs 18. By thus closing off the air at these points and by closing a slide 19 over the hopper 4, no air can enter the housing except through the tubes 13, and by entering at these points the air is directed in the most advantageous Way to produce the desired results.

IOO

combs 12, so that the combs. may be-raised and lowered by raising and lowering the free ends of the plates. The plates 2O serve to direct the lint which is acted. upon by air currents issuing from the pipes 13 which are directly over the cylinders, in a direction toward the discharge end of the machine.

24 represents concavesbeneath the cylin ders and. iny these concaves are arranged blocks 25these blocksbeing set in recesses formedz in,A the fconGaYes, as Lshown: inV Eig., VI. The form; of these blocks is-.shown-y in,.Eigs. IV and V. They aresubstantially rectangular iny transverse sectionand are eachlnade up ofa number of strips, securedftogether by rivets or bolts,26. Each alternatel strip. has a, beveled edge 27, while the intermediate strips` have, dat edges. 28. The blocks` arev placedin theconcaveswith the'faces- 27 and 28 presented toward-the cylinders, and they. are placed with theacute edges of theinclinedv facesv 27 toward. the,y approachingfor advance side of thecylinders. Thus thereis presented to the surface of thel cylindera, series ot'` right-angle rests 29, which receivel the seeds, `and as the brushes lor bristles move pa st,tlie.blocks,l the seedsare turned and. rubbedbetwcen thesharp .edges of the block-s, and the brushes, and the lint thus ettectually removed from the seeds.

As shownintlig.y VI the blocks- 25 areV placedk with their faces at an angle to the face of the cylinders, so that the seeds readily enter the triangular spaces between the forward edges of the blocks and the cylinders,

' and entering here they are thoroughly operated upon by the rubbing action between the blocks andcylinders.

I claim as my invention- 1. In. a` machinefordelinting cotton seeds, the combination of a closed casing, the cylinders having bristles, means for rotating the cylinders, the, concaves arranged beneath the cylinders, and a series of blocks built up of alternate'bevel'edl andstraight edges respectlively and set within the concave at an angle to the peripheries'. of the; cylinders1V thereby forming triangularspaces intozwhich-the seeds andlint are! collected and.' turned among themselves, as. they pass` from one# block to another; substantially'as described.

2. In.` a'machinelfor. delintingscotton'.seeds,
